Y chromosome introgression between deeply divergent primate species.
Article in Nature communications, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hybridization and introgression are widespread in nature, with important implications for adaptation and speciation. Since heterogametic hybrids often have lower fitness than homogametic individuals, a phenomenon known as Haldane's rule, loci inherited strictly through the heterogametic sex rarely introgress. We focus on the Y-chromosomal history of guenons, African primates that hybridized extensively in the past. Although our inferences suggest that Haldane's rule generally applies, we uncover a Y chromosome introgression event between two species ca. six million years after their initial divergence. Using simulations, we show that selection likely drove the introgressing Y chromosome to fixation from a low initial frequency. We identify non-synonymous substitutions on the novel Y chromosome as candidate targets of selection, and explore meiotic drive as an alternative mechanism. Our results provide a rare example of Y chromosome introgression, showing that the ability to produce fertile heterogametic hybrids likely persisted for six million years in guenons.
